The nurse is providing pre-procedure teaching about an ultrasound. The nurse informs the patient that in preparation for an ultrasound of the lower urinary tract the patient will require what?
A) Increased fluid intake to produce a full bladder
B) Intravenous administration of radiopaque contrast agent
C) Sedation and intubation
D) The injection of a radioisotope
Ans: A
Feedback: Ultrasonography requires a full bladder; therefore, fluid intake should be encouraged before the procedures. The administration of a radiopaque contrast agent is required to perform intravenous urography studies such as an intravenous pyelogram. Ultrasonography is a quick and painless diagnostic test and does not require sedation or intubation. The injection of a radioisotope is required for nuclear scan and ultrasonography is not in this category of diagnostic studies.
